IMPROVEMENT IN METALLIC SEALS.

Specification forming part of Letters Patent No. 176,290, dated April18, 1876; application tiled March 21, 1876.

To all whom it may concern:

Be it known that I, ALPHONSE FRIEDRIGK, of Brooklyn, in the county ofKings and State of New York, have invented a new and Improved MetallicSeal; and I do hereby declare that the following is a full, clear, andexact description of thesame, reference being had to the accompanyingdrawing, forming part of this specification, in which- Figure I shows,respectively, a side, edge, and end view of my improved form ofsoftmetal button for a metallic seal. Fig. 2 shows a side, edge, and endview of a modification. Fig. 3 shows a side and edge view of the form ofbutton shown in Fig. 1 compressed about the shackle-wire. Fig. 4 shows aside and edge view of the modification shown in Fig. 2, compressed aboutthe shackle-wire. Fig. 5 is an end view of Fig. 4, taken on the sectionline a: as, through the wire.

My invention consists in certain improvements upon the metallic seal forwhich Letters Patent were granted me March 14, I87 6. The seal, aspatented, shows a shackle-wire with a soft-metal button constructed withtwo heads or disks connected by a shank or stem, and so arranged thatwhen the wire is wrapped or twisted around the stem and the edges of thedisk compressed into a single thin milled flange, the latter preventsthe opening of the two disks without detection. The seal, as thusconstructed, is a good one, and will probably defy allattempts to tamperwith the same; but, to make it still more secure, I have constructed oneof the disks with a pro jecting eye or a perforated car, through whichperforation the ends of the wire are passed before twisting them aroundthe stem. This confines the branches of the shackle-wire at the edge ofthe button with a continuous ring of metal, and obviates the possibleseparation of the thin parts of metal forming the flange, and thusprevents the opening of the said flange by pulling apart the branches ofthe shackle-wire.

In the drawing, A represents the shacklewire, and B the soft-metalbutton which secures the ends of the same.

constructed with two heads or disks, a a, and a connecting stem orshank, b, which latter This button is may or may not be perforated, asdesired. As so far described, the button does not differ in anyparticular from that patented by me as aforesaid. the button, however,is cast or formed a projccting eye or perforated ear, 0, through whichthe branches of the shackle-wire are passed before being twisted aboutthe shank. After the edges of the disks are brought together andcompressed into a thin flange, the shacklewire, instead of being in theline of junction of the two edges of the disks forming the flange, areupon one side of the seal entirely, and surrounded by a ring of metal,which renders it impossible to separate the edges of the flanges bypulling apart the branches of the shackle-wire without breaking thecontinuous ring of metal forming the eye.

In fastening the wire about the stem of the button it may be twistedabout the same as many times and in as many forms as may be be desired,and it may or may not be passed through the perforation in the stem,according to circumstances.

As a modification of my invention, instead of forming an eye upon onedisk, I may form an imperforate ear or lug, d, Fig. 2, upon each of theopposite d-isks, which ears are so relatively arranged that, whencompressed, they lap over the joint in the flange upon opposite sides ofthe wire, and thus operate, in a similar manner, to prevent the wiresfrom being pulled apart to open the flange.

Having thus described my invention, what I claim as new is 1. Thesoft-metal button, having a perforated ear, 0, projecting from its outeredge, in combination with the shackle wire, having both ends passedthrough one and the same perforation in said car, as and for the purposedescribed.

2. The shackle-wire A of a metallic seal in combination with asoft-metal button, con sisting of two connected disks, provided with aprojecting eye or its equivalent, as and for the purpose described.

ALPHONSE FRIEDRIOK.
